Abstract

This article reviews the use of transmission electron microscopic techniques for the microstructural characterization of dislocation substructures induced in certain ferritic alloys. Solution-treated Fe-25Cr-4Al, Fe-25Cr-2Al, Fe-19Cr-4Ni-2Al and aged Fe-19Cr-4Ni -2Al alloys were subject to cyclic deformation in air at various total strain amplitudes. The results showed that loop patches, extended wall, and labyrinth structures that are typical substructures developed in fatigued f.c.c. metals also tend to form in ferritic Fe-25Cr-2Al alloy containing higher C interstitials. Furthermore, the effects of Ni addition and aging heat treatment on the development of dislocation substructures in the Fe-19Cr-4Ni-2Al alloy are also discussed. © 1991.
